The autonomous ecological house is a form of individual house that has everything to appeal to those concerned with the future of the planet, while wishing to prioritize well-being and energy savings. Zoom in on this type of construction.
What is a stand-alone ecological house?
In short, a self-contained ecological house is a house that is energy independent. This means that the house itself produces all of the energy it needs. A self-contained house is also called a zero energy house. In fact, it consumes very little energy, around 100 kWh per m² per year. The use of solar panels or installations such as a Canadian well can meet the low energy needs of the house.
What are the characteristics of a stand-alone ecological house?
A self-contained green house uses photovoltaic solar panels and / or wind power. It is equipped with a heated floor that works with solar energy. To reduce energy loss, it has thick walls, high-performance insulation, triple glazing and a green roof.
How to calculate your electricity needs?
To determine how many panels you will need, start by consuming your electrical appliances.
To do this, multiply the power in watts (W) of each device by the time of use over a day. Then add it all up to get a result in watts per hour. Keep in mind that photovoltaic production varies depending on the latitude and the seasons.
The water self-sufficiency of an autonomous ecological house
The autonomous house is also characterized by its water autonomy. To do this, it includes a rainwater recovery and water treatment system (lagoon purification process). The collected water is thus used for the garden, the bathroom, the dishwasher, the toilets and for washing the car.
Self-consumption: what is the point?
Self-consumption has significant advantages in that you produce your own energy at a lower cost. Indeed, if the storage of solar energy represents a very interesting alternative, even if the solar kits equipped with batteries will require regular maintenance which will increase the cost of a purchase that is supposed to save you a lot of money. Self-consumption is therefore one of the best ways to have economical lighting.
